Abstract
A method of encoding interlaced, full motion digital video image data. The digital video image data has two interlaced fields per frame with luminance and chrominance components, where the chrominance components are uncorrelated between adjacent fields. The method encompasses applying one field of chrominance information to both luminance fields of a frame. This encodes chrominance components at one quarter the spatial resolution of the luminance components.
